Hi All,
I am running lmbench version-3.0-a9 on two embedded platforms.
P1 - Xscale processor with 2.6.21.1 linux kernel
P2 - OMAP3430 processor with 2.6.24.7 linux kernel

I want to know why the cost of page fault in case of P2 is more as the file
size increases.
But I dont know where to start. Please give directions
Thanks for your time
